Limit init_subclass test above python 3.6

2020-07-08T21:54:14+00:00

The commit for I1654befe9eb1c8b8e7fc0784bdbe64284614f0ea #5357
runs the test on all Python 3 versions, however we need to limit
at least python 3.6 for this.

Add **kw support to DeclarativeMeta.init

2020-07-06T20:43:06+00:00

Added a ``**kw`` argument to the :meth:`.DeclarativeMeta.__init__` method.
This allows a class to support the :pep:`487` metaclass hook
``__init_subclass__``.  Pull request courtesy Ewen Gillies.

Pass connection to TablesTest.insert_data()

2020-04-15T15:12:59+00:00

towards the goal of reducing verbosity and repetition
in test fixtures as well as that we are moving to
connection only for execution, move the insert_data()
classmethod to accept a connection and adjust all
fixtures to use it.

Remove support for python 3.4

Also remove no longer used compat code

Simplified module pre-loading strategy and made it linter friendly

2020-03-07T22:50:45+00:00

Introduced a modules registry to register modules that should be lazily loaded
in the package init. This ensures that they are in the system module cache,
avoiding potential thread safety issues as when importing them directly
in the function that uses them. The module registry is used to obtain
these modules directly, ensuring that the all the lazily loaded modules
are resolved at the proper time

This replaces dependency_for decorator and the dependencies decorator logic,
removing the need to pass the resolved modules as arguments of the
decodated functions and removes possible errors caused by linters.

Consult is_attrbute flag to determine descriptor; enable for assoc proxy

2019-06-15T02:44:59+00:00

Fixed bug where the :attr:`.Mapper.all_orm_descriptors` accessor would
return an entry for the :class:`.Mapper` itself under the declarative
``__mapper___`` key, when this is not a descriptor.  The ``.is_attribute``
flag that's present on all :class:`.InspectionAttr` objects is now
consulted, which has also been modified to be ``True`` for an association
proxy, as it was erroneously set to False for this object.

Implement new ClauseElement role and coercion system

2019-05-18T21:46:10+00:00

A major refactoring of all the functions handle all detection of
Core argument types as well as perform coercions into a new class hierarchy
based on "roles", each of which identify a syntactical location within a
SQL statement.  In contrast to the ClauseElement hierarchy that identifies
"what" each object is syntactically, the SQLRole hierarchy identifies
the "where does it go" of each object syntactically.   From this we define
a consistent type checking and coercion system that establishes well
defined behviors.

This is a breakout of the patch that is reorganizing select()
constructs to no longer be in the FromClause hierarchy.

Also includes a rename of as_scalar() into scalar_subquery(); deprecates
automatic coercion to scalar_subquery().

Add informative failure modes to _DeferredMapperConfig

2019-01-31T03:06:27+00:00

Added some helper exceptions that invoke when a mapping based on
:class:`.AbstractConcreteBase`, :class:`.DeferredReflection`, or
:class:`.AutoMap` is used before the mapping is ready to be used, which
contain descriptive information on the class, rather than falling through
into other failure modes that are less informative.

Improve error messages in the area of loader options

2019-01-26T01:59:08+00:00

Improved error messages emitted by the ORM in the area of loader option
traversal.  This includes early detection of mis-matched loader strategies
along with a clearer explanation why these strategies don't match.

Add deprecation warnings to all deprecated APIs

2019-01-23T23:10:06+00:00

A large change throughout the library has ensured that all objects, parameters,
and behaviors which have been noted as deprecated or legacy now emit
``DeprecationWarning`` warnings when invoked.   As the Python 3 interpreter now
defaults to displaying deprecation warnings, as well as that modern test suites
based on tools like tox and pytest tend to display deprecation warnings,
this change should make it easier to note what API features are obsolete.

See the notes added to the changelog and migration notes for further
details.
